An object of this invention is to provide an eillcient form of heating, power and lighting equipment for houses and small buildings of various kinds.

Another object is to combine such equipment with either hot water or steam heating apparatus, as well as providing hot water for domestic use.

These and other objects, as will hereinafter appear, are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawing, in which The figure is a side elevation partly in section showing the heating and lighting equipment applied to a hot water heating system.

The embodiment illustrated comprises essentially an internal combustion engine A located preferably in the basement of the building to be heated, and adapted to drive an electric generator B, preferably of the alternating current type, the water from the cooling jacket of the engine being drawn from the bottom of a heating tank C and returned to the top of the same, the waterin this tank also being heated by the exhaust gases from the engine passing through a coil D in the tank, the hot water from the top of the water tank C passing to heating coils E for heating rooms in a well known manner. Water for domestic use is also heated in a heat transfer coil F and stored in a hot water storage tank G.

The engine A preferably runs continuously at substantially uniform speed which may be accomplished by any suitable speed governing devices well known in the art, and which accordingly need not be described or illustrated in detail herein; and has a storage battery (not shown) for supplying electric current for the ignition. This engine vvill operate successfully on kerosene or distillate 'which is stored in an underground tank I II and 'arried to the carburetor of the engine through a pipe II. This tank is filled from out of doors through a filling pipe I2, the tank being vented to the atmosphere through a pipe II. The engine and generator are preferably mounted on a suitable base ll which is mounted on springs I! to absorb vibration of the engine and to prevent noise. The engine is also preferably enclosed in a cabinet or room It which is rendered substantially sound proof. A flexible met a1 exhaust pipe I'I extends through the side otz,

this cabinet and connects with the coil D. the opposite end of the coil connecting through a pipe II with the stack I. through which the exhaust gas is to the atmosphere.

The bottom of the tank. connects through- (Cl. 290-2) "suitable pipes or fittings and a flexible hose 2i with the bottompof the engine cooling jacket, the

top of the jacket leading to a pump 22 which is driven in any suitablemanner, as by means of a belt 23, from the engine crank shaft, A flexible hose 24 leads from the pump 22 to a riser 25 which leads into the topof the water tank C. Thus when the engine is running a continuous stream'of water passes from the bottom of the tank C through the engine cooling Jacket and back to the top of the tank, thus heating the water in the tank. The riser 25 extends vertically and has lateral pipes 26 for carrying'water to the various radiators E, the return from these radiators (of which only one is shown) be.- ing through pipes 21, 28, and 20.

Electric current from the generator B is carried to a suitable switchboard 29 which has a distributing line 30 for furnishing power and light to the building. Connected to this is a line 3| which connects to an electric heating unit 32 which extends into the tank C so as to heat the water therein, this heating unit being connected in series circuit with an aquastat 33 of a well known type which is set to close the circuit 3| through the heating coil 32 when the temperature of the water in the top of the tank falls below 180 F. and to open when the temperature of this water reaches 190 F.

A drain pipe 34 connects through an electrically operated valve 35 with the riser 25 and leads to adrain, not shown. The electric control for the valve 35 connects with the line 3| through an aquastat 36 which is set to open the valve 35 when the temperature of the water in the top of the tank exceeds 200 F., and to close this valve again when the temperature of this water falls to say 190 F. The temperature and pressure of the water in the top of the tank Cis shown by a combination pressure gauge and thermometer 31. The water in the tank C is supplied through a pipe 38 and controlled by means of an automatic water feeder 39 of a well known type.

The temperature of each individual radiator E may be controlled by means of a valve 40 connected to each radiator, and the water flowing to all the radiators may be controlled by means of a valve 4| operated by an electric coil 42 connected in series circuit with a thermostat 4'3 loc'atedin some convenient part of the building and connected through a line with the generator. Thus when the temperature at the thermostat exceeds a predetermined amount, the coil 42 closesthe valve ll thereby preventing hot waterfromimtherlserlltotheradiators. The thermostat 43 will be set to open andclose onatemperaturediiferentiaiofilto3 drahrenheitsoastomaintshiasubstan- .tiailyuniform Hotwaterfordomesticuseisstoredinthetank Gwhichhasapipelileadingtothebottomof. theheattransfercoilnthetopofthiscoilcom' convection producing a circulation down through the pipe It and up through the pipe 40, as indi-V cated by arrows.

While I have shown and desi nated but a few embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart fromthespiritandscopeottheinventionas disclosed in the appended elahm.
